Replace Window Units with One Clean Ductless System in Austin
Updated September 2026
If you’re tired of juggling window units every summer, loud, dripping, blocking your view, one ductless mini split can cool your whole home quietly and efficiently. No ductwork, no hassle. Just consistent comfort in every room, even when the Texas heat hits triple digits.
At Old West Minisplits, we make the switch simple. Flat-rate pricing, no hidden fees, and no in-home sales pitch. We install the system, clean up, and leave you with a setup that works better and costs less to run than those old window units.
Why Ditch Window Units for a Mini Split?
Window units are cheap upfront, but they come with trade-offs. They cool one room at a time, block natural light, drip condensate on your siding, and run loud enough to drown out conversation. Worse, they’re inefficient, your electric bill climbs every time you crank them up.
A ductless mini split solves all of that. One outdoor unit powers one or more indoor heads, each controlled separately. No ductwork means no energy loss, and the system runs quietly enough that you’ll forget it’s on. Since it’s a heat pump, it handles both cooling and heating, so you’re covered year-round in Central Texas.
Flat-Rate Pricing, No Surprises, No Sales Visit
Most local HVAC contractors quote you in person, then tack on fees for line sets, refrigerant, or cleanup. We don’t. Old West Minisplits posts flat installed prices upfront: $2,000 for one zone, $3,700 for two, $5,400 for three. That covers the equipment, labor, line set, standard electrical, refrigerant, testing, and cleanup. We even swing by Home Depot for touch-up paint if we scuff a wall.
The only exceptions are rare: a very long line set, a panel upgrade your house already needed, or an unusually difficult mount. We’ll tell you about those before we start, not after.
What You Get with Old West Minisplits
We install ductless systems from brands like Mitsubishi, Daikin, and LG, units built to handle Central Texas heat. The outdoor compressor sits quietly outside, while the indoor heads mount high on the wall or ceiling, out of the way. No ductwork means no dust or allergens blowing through your home, and no energy wasted pushing air through leaky old ducts.
Our service area covers Austin and the I-35 corridor, from Waco/Killeen down to San Antonio. Same flat pricing everywhere, no extra charges for driving farther out.

Straight answers
Do I need a permit for a mini split in Austin?
Yes, but we handle it. Permits are required for HVAC work in Austin, and we pull them as part of the job. You won’t have to deal with the city or extra paperwork.
How long does the install take?
Most single-zone installs take one day. Two or three zones might take a day and a half. We’ll give you a clear timeline when we schedule the work.
What if my electrical panel isn’t big enough?
If your panel needs an upgrade, we’ll let you know upfront. It’s not common, but if it’s necessary, we’ll quote the extra cost before we start. No surprises.
Can I keep one window unit as a backup?
You can, but you probably won’t need to. Mini splits are reliable and built to last. If you’re worried about redundancy, we can discuss adding a second zone instead.
